SPECIFICATION forming part of Letters Patent No. 555,798, dated March 3, 1896. Application filed July 8, 1895. Serial No. 555,215. (No model.)

T0 at whom it may concern.-

Be it known that I, WILLIAM R. BAKER, of Watertown, in the county of Jeiterson, in the State of New York, have invented new and useful Improvements in Flushing Devices for \Vater-Olosets, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

My invention relates to certain improvements in flushing devices for water-closets which dispense with the service-box and furnish the necessary afterwash, and the principal object of my invention is to provide means to open the base of the dash-pot automatically and simultaneously with the opening of the main valve.

To this end my invention consists in the combination, with a pipe or chamber closed at one end and connected at the other with a supply-pipe, of an outlet, a dash-pot within the chamber at the closed end, a hollow piston, a valve in the piston, a hollow piston-rod connecting the hollow piston with the main valve atthe opposite end of the chamber, an aperture in the side of the dash-pot, a lever connected to the piston-rod to reciprocate the same, and means also connected to the lever to open and close the aperture in the dash-pot; and my invention consists in certain other combinations of parts hereinafter described, and specifically set forth in the claims.

In the drawings, Figure 1 is a horizontal longitudinal sectional view of the device, showing the working or movable parts in their normal position. Fig. 2 is a horizontal longitudinal sectional view showing the movable parts in their operative position. Fig. 3 is a side elevation of the device. Fig. 4 is a cross-sectional View of the small sliding valve having the grooved stem carried in the hollow piston, and Fig. 5 is a side elevation of the lever connected with the screw entering the aperture or opening in the base of the dash-pot.

Referring specifically to the drawings, A represents the main pipe or chamber having a cylindrical form extending horizontally and having its right-hand end closed by a cap a. At the cappecLend of the chamber and preferably integral with the latter is a dash-pot or tube B, concentric with the walls of the chamber A. The end of the dash-pot toward the cap is closed by the latter, but the opposite end is left open. Within the said dashpot is a conical and hollow piston-head D, divided centrally in two parts by a partition d. The part on the side of the partition (Z toward the cap is open, but the other part is closed on its sides. Extending through the center of and sliding longitudinally in said partition is a grooved stem g, having a valve on each end thereof, so that the aperture in the center of the partition in which the stem works may be closed at the end of each movement of the stem.

D is the piston-rod of the piston described. Said rod is hollow or formed of a pipe which opens into the closed part of the hollow piston-head, extends centrally in the chamber A, is movable longitudinally therein, and is supported by bearings c 0, extending from the inner side of the chamber.

On the end of the piston-rod D opposite to that carrying the piston is a valve 0, formed preferably of a leather disk and a metal disk of somewhat less diameter than the interior of the chamber A. This valve engages an annular seat formed by one of the supports 0, and when in engagement with its seat the inlet F is closed. A coil-spring f, extending between the valve 0 and a rim f in the inlet pipe, serves to close said valve and force the piston-rod to the right and within the dashpot. In the wall of the dash-pot and to the right of the piston-head, when it rests in its normal position, is an outlet or aperture i. This outlet is adapted to be closed more or less to regulate the flow of water from the dash-pot and thereby control the duration of the flow of water for the afterwash by means of a screw I passing through the chamber and having a tapered or pointed end entering the outlet e.

G is a main outlet of the, chamber, which is connected by a pipe with the closet.

It will be noticed by reference to Fig. 1 that when the parts are in their normal position all have moved to the right to the fullest extent, due to the action of the coil-spring and the pressure of the water in the piston-head D upon the small sliding valve 9. The weight of the free end of the operating-lever K, pivoted to an arm or bracket L projecting from the chamber A, draws the operating-rod H, which passes through the center of the cap a, to the right, so that there is nothing to prevent the movement of the small valve 9. The operating-rod H is provided with a collar h,

which may serve to limit its movement to the right; but this is unnecessary, for the reason that the nut on the inner end of and bearing on the piston-head will form a suflicient limiting-stop. The opposite end of the rod is provided with a shoulder Z and a screw Z to hold a sleeve which is on one end of an angular connecting-rod J, extending along one side of the chamber to the short depending arm of the operating-lever K. hen the lever K is raised to operate the device, the rod H slides through the piston-head D for a short distance without operating it to open the small valve g and allows the water to flow through the hollow piston-rod D into the closed part of the piston-head and through the partition d into the dash-pot B, the water passing through the partition by means of the grooved or channeled stem of the valve. Then the collar It on the rod strikes the end of the piston-head and the latter is forced to the left against the action of the spring f until said head strikes one of the supports 0, as shown in Fig. 2 of the drawings. In this position the large inlet-valve C is open wide, allowing the water to flow freely to and through the outlet. Upon the release of the lever K the said movable parts move slowly to the right, depending upon the extent of the opening 1; in the side of the dash-pot until all of said parts have resumed their normal position.

The device operates easily and noiselessly. By passing the water from the inlet F to the dash-pot B through the piston-rod all possible leakage is prevented.

In order that the screw I may be operated automatically or opened and closed simultaneously with the movements of the operatinglever K, I provide the screw with a rather coarse left-hand thread, secure an arm I to the head of the screw, as shown in Figs. 3 and 5, and provide the said arm with an adjustable screwj to bear on a lug or stop 7t on the side of the connecting-rod J. The arm I is crooked or bent in toward the chamber to allow the rod J to lie near the same. The screw extends through the said arm on an angle, so that a movable back-stop m on the rod J will not interfere with its adjustment. The movable back-stop m is provided with a slot, as shown in Figs. 1 and 2, with a screw n passing therethrough and entering the rod. hen the device is in its normal position, the screw I has closed the outlet '2', the lug 7.; being in engagement with the end of the adjustable screw j. hen the operating-lever K is raised sufliciently, the stop m comes in contact with the arm or lever I and moves it to the left, which turns the screw I to open the aperture t' to allow the water to enter the dash-pot. During the return of the operating-lever K to its normal position the screw I slowly closes the aperture '0' during the latter part of its movement. Awire screen may be placed in the inlet to keep the dirt from the working parts.

Any matters shown and described herein but not claimed are not dedicated to the publie, but are claimed in another application for Letters Patent, Serial No. 524,551.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-
